Levittown sits in IECC Climate Zone 4A (Mixed-Humid), which determines the insulation R-values and air-sealing standards required by 2018 IECC (statewide under the PA Uniform Construction Code, Act 45). Local electric service is provided by PECO, with natural gas typically served by PECO.
Levittown’s identical 1950s homes have predictable leakage patterns: original aluminum windows, uninsulated rim joists, and forced-air systems with ductwork in unconditioned crawlspaces or attics. Testing routinely reveals 10-15 ACH50 before retrofit work.
Understanding the Blower Door Test in Levittown
A blower door test determines the air changes per hour (ACH) of a house or building — the rate at which the interior air volume is being replaced by outside air. Some ventilation is essential (stale air out, fresh air in), but too much wastes energy and can cause drafts, condensation, and moisture issues.
A blower door test in Levittown, PA catches air leakage problems early, so homeowners and builders in Bucks County can fix them before they become comfort or energy-efficiency complaints.
What Our Clients Say
Saima Faiz — October 2024
I recently contacted Local Energy Audits for help with a suspected duct leak. From the start, they asked all the right questions and even requested pictures to better understand the situation. Based on the information I provided, they recommended a specific service, which, surprisingly, they didn’t even sell. They didn’t charge me anything for their time, and the advice they gave was invaluable. Their honesty, professionalism, and genuine desire to help really stood out. I highly recommend them.
Max Young — September 2024
Frustrated with my high electric bills — despite an efficiency drive in lighting and appliances — I suspected HVAC was to blame but didn’t know where to start. Research suggested an energy audit, and I’m very happy I chose Local Energy Audits. Ori was extremely professional, thorough, and on-time. After the blower door test, he walked every room with me, patiently reviewing leaks and possible fixes. Particularly given the new federal tax credits, I found the price extraordinarily reasonable. Highly recommend.
Robin Rafkin — June 2024
I had called numerous companies and had numerous individuals to our house. No one could figure out the issues. Ori explained everything and fixed the issues. He and his crew are wonderful!

How Is the Blower Door Test Conducted in Levittown?
For your blower door test in Levittown, PA, the technician ensures all exterior doors and windows are sealed and interior doors stay open. An adjustable aluminum frame with a fabric panel is installed in a central exterior door. A calibrated fan depressurizes the home to 50 Pascals — roughly the force of a 20 mph wind pressing on the house.
As air is drawn out, outside air rushes in through unsealed spaces. A manometer measures fan airflow against the pressure differential, and the result converts to air changes per hour (ACH).
What Counts as a Passing Score in Bucks County?
Levittown, PA enforces the 2015 IECC (or newer), which sets a 3 ACH50 maximum for new residential construction. Your blower door test result must come in at or below that number to pass.
For context: a tight, well-built new home typically reads 1.5–2.5 ACH50. Older homes without any air sealing work can read 8–15 ACH50. The goal of testing early in a build is to catch issues while they’re still easy to fix.
Why Do I Need a Blower Door Test in Levittown?
PA enforces the IECC, requiring blower door tests on residential construction and substantial renovations.

How to Pass a Blower Door Test in Levittown, PA
- Think about air leaks before testing begins. Don’t wait for the test to reveal problems — plan the air barrier from day one.
- Install an effective air barrier (Tyvek, ZIP sheathing, or equivalent) and make sure every seam is sealed with quality tape.
- Place insulation with the correct R-value for PA’s climate zone and verify full coverage throughout the envelope.
- Seal all penetrations in exterior walls — plumbing, wiring, HVAC lines — with caulk or spray foam.
- Install doors and windows properly, with complete weatherstripping and caulk at the frame.
- Seal any openings between conditioned and unconditioned areas (basement rim joists, attic hatches, crawl space access).
- Review the applicable air barrier checklist for your jurisdiction. Philadelphia’s version is downloadable here; other Bucks County municipalities use similar documents.
- Local Energy Audits identifies leaks on-site using thermal imaging and can help seal them in-the-moment with caulk and high-quality spray foam.
- Over 90% of the time, we achieve a passing score in under two hours and hand you the documentation needed to close your permit.
Getting Ready for Your Blower Door Test
Preparation is straightforward. Before we arrive in Levittown, turn off all HVAC equipment and any continuously-running exhaust fans (bathroom, kitchen, dryer). When we show up, we walk through the house to make sure every exterior door and window is closed, including doors to unconditioned areas like garages and basements.
The calibrated fan mounts in a central exterior door, and we depressurize to 50 Pascals. With the home under negative pressure, leaks become easy to feel and easy to spot with a thermal imager. Most Bucks County homes with modest leakage can be brought to passing during a single visit using the caulk and spray foam we bring along.

Frequently Asked Questions
What ACH50 do I need to pass the blower door test in Levittown, PA?
Under 2018 IECC (statewide under the PA Uniform Construction Code, Act 45), the pass threshold is 3 ACH50 or lower for most residential construction. Newly built homes in Levittown with attention to air sealing typically achieve 1.5-2.5 ACH50.
How long does a blower door test take in Levittown?
Most blower door tests in Levittown take 1-2 hours total, including setup, testing, leak identification with thermal imaging, and documentation. Minor sealing work, if needed, can often be done on-site.
Does my PA home need mechanical ventilation?
If your Levittown home tests at 3 ACH50 or tighter (which current code requires), 2018 IECC (statewide under the PA Uniform Construction Code, Act 45) also requires balanced mechanical ventilation per ASHRAE 62.2 to maintain indoor air quality. This is typically an ERV or HRV system sized to the home.
What insulation R-values are required in Climate Zone 4A?
For Levittown (4A (Mixed-Humid)): R-49 ceilings, R-20 walls (or R-13 + R-5 continuous), and R-10 continuous or R-13 cavity for basement walls per 2018 IECC (statewide under the PA Uniform Construction Code, Act 45). These minimums drive what your home needs to pass overall energy code.
